Projected Reservoir Rating Curves based on volumetric elevational sedimentation rates
The TWDB's Water Availability Program has developed projected reservoir rating curves for 80 major water supply reservoirs in Texas based on the distribution of sediment volume by reservoir elevation. These ratings curves are developed at 0.1-feet elevation interval for most of reservoirs listed in this page for the full available elevation range in each reservoir.
Regional Water Planning Groups in Texas are required to consider anticipated reservoir sedimentation rates when they simulate reservoir firm yields using the state's Water Availability Models (WAMs). Presented here are simplified projected rating curves (i.e., rating curves for 12 elevation points at equal elevation interval, suited for input to the WAMs) for 80 major water supply reservoirs for the water planning decades 2030 through 2080.
For more information on the volumetric elevational sedimentation rate method, please see this draft paper. If you have more questions, please contact Dr. John Zhu or the Surface Water Division.
